NAMIJU took delivery of the 2MW/8.23MWh Sakaiminatoshi Shinyacho 1158 Power Storage Station in Sakaiminato City, Tottori Prefecture, developer Enblue announced on November 11, 2026.
According to the statement, the asset uses PowerX battery systems and was completed in October 2026. Enblue handled land acquisition, grid connection and permitting, equipment procurement, and construction management.
The facility is the first of three grid-scale battery storage projects that NAMIJU is investing in, its website shows. The other two, in Hashimoto City, Wakayama Prefecture, and Omaezaki City, Shizuoka Prefecture, are scheduled for completion in December 2027 and March 2028, respectively. Their capacities are likely to be similar to or smaller than the Tottori asset’s based on disclosed footprints.
Primarily a domestic and overseas residential and commercial real estate investor, NAMIJU also leases aircraft. As of the end of FY2024, its total assets stood at 16.4 billion yen, its website shows. The company does not appear to have invested in energy infrastructure prior to its entry into battery storage.
